To send a distress message

distress button for longer than 3 seconds. For short step-by-
step instructions how to proceed when sending a distress
message see Emergency calls on page v.
When the distress signal is sent, CH70 and
Tx appear in the display. A two-seconds
steady tone is heard.
2. The radio watches for a DSC
acknowledgement transmission on channel
70.
3. To pause the automatic resend procedure
press the soft key PAUSE.
4. To annul the distress message press the soft key ANNUL. See also To cancel
own distress on page 23.
5. When a distress acknowledgement is received, a pop-up window is
displayed. Start distress communication on channel 16 to inform about your
distress situation.
If no distress acknowledgement is received within a period of 3,5 to
4,5 minutes, the distress message will automatically be
retransmitted.
